i RUDOLPH J. SAILER, or TOWNLEY, New JERsnr-Assenoa "fro TransilvaniaMANU"-A FACTURING COMPANY, on` ELIZABETH, Nnwannsnx e consonancia orxnnwg' ranma/inn, Y' i 1 Appncation sieaiune 5, 1929., serial l:n.aeasaa-This invention' relates to a folderffor use with sewing machines forforming a facingstrip upon the edge of a body-fabric of a Y shirt.

forcements customarily-formed upon adjacent front portions of a shirt orother gar.- mentV and upon yone of these facing-strips ybuttons ,I aresecured which are .adapted to enter buttonholes formed in the otherfacingstrip for closing the fro-nt of the shirt or garment.- The objectyofthe present invention is the construct-ion of a folder wherebythefacing strip is formed vupon the marginal portion of a body-fabricwithout the use of a separate fabric-strip. Y Y

According to the present invention lthe folder is constructed with aplurality of superposed guideplates with a. tuck-forming l''nn'arginalportion of the fabric-section intol the `reentrantv fold made by thetuck-forming channel for concealment of the rawv edge of l theY fabric.

" The invention is illustrated in the accom-v panying drawings in whichFig. 1 is aplan view of the folder attached to the cloth-platev of asewing machine. Fig. 2 is a side-elevation of the folder showing it inoperative Y. relation to the needle and presser-foot .of the sewingmachine. Figs. 3 and 4 are sectional elevatio-ns, on an enlargedscale,1on lines 3 3 and 4-4, respectively, of Fig. 1 -Fig 5..

and Fig. 5 is a diagrammatic view illustrat-'l-` infr the worlproduced*bythe folder. The folder is shown mounted'upon a sewing machmehaving any'suitable stitch-form lng mechanism in which a pair of spacedv, needles 1 operate through needle-holes 2 in a presser-foot 3 above athroat-plate licarried by the cloth-plate 5. Y A feed-dog -operates inlslots (not shown) in the throat-plateas will be understood by thoseskilled in the art.

Having thus set forth the nature of the invention, What I claim hereinis l. A folder comprising afabric-supporting plate, a Wall overhangingand sustained by one edge of said fabric-supporting plate, an arborspaced above and supported by said overhanging Wall and extendinglaterally beyond said edgeof the fabric-supporting plate and ahein-scroll embracing said arbor and having a free edge disposed betweensaid fabric-supporting plate and said overhanging Wall.

2. A folder comprising a base-plate, a guiding-plate of eshapedcross-section, and a henrscroll sustained at one side by said base-plateWith one of its free edges affording aI support for the intermediatelimb of the S-shaped guiding-plate and its other free edge being spacedbetween the lovver and intermediate limbs of said Sshaped guidingplate.p

3. A. guide for sewing machines comprising a base-plate, a hem-scrollsecured at one side to said base-plate and a tuckeformingchannel-1nember Carried by the other side of said hem-scroll remote fromsaid base-plate- In testimony whereof, l have signed my name to thisspecification.
